1 Tar-Calmacil was the first to officially use an Adûnaic name. The Númenórean nobility appears to have not spoken Adûnaic at all in the first centuries. Most names prior to Calmacil are therefore likely not contemporary, but were invented by the Númenóreans after they had become alienated from the Elves.

2 Upon his father Elros' death, Vardamir did not take up the Sceptre of the King but instead abdicated in favor of his son. However, he is counted as the second ruler having nominally ruled for one year.

5 Tar-Ardamin is omitted from the list published in The Lord of the Rings, but he does appear in Unfinished Tales. In Appendix A of The Lord of the Rings, Tar-Calmacil was followed by Ar-Adûnakhôr. His name was apparently dropped by error.

6 As the eldest child and according to laws of succession changed since the reign of Tar-Elendil, Míriel was the rightful Queen, but was forced to wed her cousin Ar-Pharazon who usurped the throne.
